Honestly, Sony TVs are notorious for having their mounting holes lower than other brands. I had the same issue with my Bravias recently. To save yourself the headache, go with something universal and heavy-duty. I personally use the ECHOGEAR Full Motion TV Wall Mount EGLF2 for 42-90 inch TVs for my 65-inch LED and it works great. It comes with a ton of different spacers in the box, which is basically a lifesaver because Sony panels often need them for a flush fit. The best part is the extension; you can pull it out far enough to reach those side HDMI ports without skinning your knuckles. Its way cheaper than the official Sony mounts but does the exact same job. Just double-check your wall studs first... it makes swapping the screens way easier.

Just caught this thread and wanted to share what works for me. If you are swapping between different sizes like that, you really need a mount with extra vertical height on the brackets. Sony puts their VESA holes so low that a standard mount might leave your 65 inch sitting way too high if you dont plan for it. I usually recommend the Sanus VLT7-B1 Advanced Tilt 4D Wall Mount for Bravia setups. It is a bit pricier than the budget brands, but it lets you pull the TV out a few inches to get your hands behind it for those side HDMI ports without needing a full motion arm. Plus, the hardware kit is actually decent so you wont have to run to the hardware store for specific spacers. It makes swapping the screens way easier down the road since it has tons of built-in adjustment tho.

I have spent way too much time obsessing over mounting my own Sony sets, and honestly, safety is the number one thing you gotta worry about. Since you want to swap the 55 and 65 inch models, you need something with a super secure locking mechanism. I swear by the Sanus VLL5-B1 Fixed-Position Mount for 32-80 Inch TVs for this exact setup. The ClickFit system is a lifesaver because you actually hear it lock into place, which gives a lot of peace of mind when hanging an expensive OLED. Plus, it is thin enough to look clean but leaves just enough gap for side-loading cables if you use 90-degree adapters. Reliability is everything when you are mounting something that pricey.

• Make sure the wall plate is wide for lateral shifting.
• Check the weight capacity for the 65-inch LED, they can be surprisingly heavy compared to the OLED.
• Double check the VESA screws, sometimes Sony sets need specific M6 lengths. Basically, just take it slow and dont forget to make sure those brackets are clicked in tight so nothing falls!

Saw your post this morning and figured I'd chime in since mounting Sony sets can be a bit tricky. I think I remember reading somewhere that their newer OLEDs have really weird VESA placements, usually way lower on the chassis than you'd expect, which kinda messes with the center of gravity. Honestly, if you're worried about safety, I'd check out the official Sony support site or even a site like RTINGS before buying anything. They usually have detailed back panel photos and measurements for port clearance. IIRC, some people have had issues with low-profile mounts blocking those side-loading ports because they sit way too flush to the wall. Maybe look into a tilting mount? I'm not 100% sure which mount would be truly universal for both, but checking a compatibility tool like the one on the Sanus website might help tho. Better to be safe than sorry with those expensive screens.
