I was wonder exactly which screws you were refering to. Picture with back panel off. Was it the 12 or so screws at the very top edge? Any guidance is greatly appreciated.
The B is laid out a bit differently, there are more long metal strips along the top (which are attached to the actual frame of the panel) and some screws are facing up as well as out. I loosened all of those along the top which I could see.
And yes, as Lee said, there's lots of screws. That pic looked familiar!

It's not essential IMO. Folks may remember me saying that it's a single-pixel edge/contrast enhancer, one up and one over, mostly for luma than the chroma. It certainly makes the single-pixel test patterns stand out more, but it's overcooking them because they should look grey from a distance (viewed on a 1080p TV for reference), whereas they're a blown-out white with Mi4K on. Looking at it close-up also adds a very, very small amount of aliasing on fine diagonal edges because of the one-up/one-over nature of the Mi4K's single-pixel enhancement, I suppose it's there to mimic the finer pixel resolution of true 4K content.
Note that if you set Reality Creation off then the single-pixel checkerboards are completely greyed out. With RC on it DOES pass single-pixel detail, albeit at a slightly filtered frequency. (Get up close and you'll see it.) But with Mi4K on top, it exaggerates single-pixel beyond what it should actually be, and I've taken to leaving it off. (Though bear in mind that the B series doesn't even need RC on to get that single-pixel passthrough, so I also leave RC off now.) I may still enable RC/Mi4K for Sony's own Mi4K software, but I still can't figure out how they would've encoded their discs to take advantage of such processing. Special metadata my ass.
