Seeing that you want a 65" and a 75" is too large, that riles out the TCL X11L.
For the best overall experience with some caveats and compromises, I’d say maybe the LG MLA or 4 Stack Tandem RGB models or models which use similar technology from other brands.
However, for the ultimate experience once you’re not in a pitch black room, nothing should beat an X11L, RM9L (provided it’s switched to white/blue Backlight mode), QM8L, QM8K. They all have the brute force Brightness to support high density, high opacity Masks and Scanlines, while using BFI which is what is required for accurate as possible CRT simulation / emulation.
They also have R-G-B subpixel layout, which matches a CRT’s Phosphor layout. The MLA OLEDs Do not have RGB subpixel layout and with the 4 Stack Tandem RGB displays the first subpixel is not the Red subpixel. Also with WOLED technology, there’s an unorthodox gap between where the white subpixel lies. This leads to some TVL and Mask combinations looking a little distorted, with uneven spacing between the coloured stripes especially when compared to what’s possible on an R-G-B or B-G-R subpixel layout LCD.
R-G-B / B-G-R vertical striped subpixel layout LCD can render all combinations of Mask, Scanlines and TVL as intended.
I have yet to get CRT Beam Simulator working and looking properly on my TV - a TCL QM751G, however the TV has built-in hardware Strobing/LED Backlight, which for all intents and purposes should be just as good if not better than CRT-Beam Simulator.
A very good alternative to that which auto compensates for the Brightness loss is Adaptive-Strobe-Koko! That’s what I’m using these days because my TV hasn’t the brightness headroom when I run the TV’s built-in hardware BFI.
One good thing about the hardware BFI is that it can be used even at 60Hz refresh rate.
