> The pixel glow

Can be decently emulated with more modern shaders that rely upon HDR, provided your HDR monitor is bright enough, which most are not. My display can do a reasoable job with 1600+ nit peaks, and 1200 nits sustained. OLED's are not really capable here due to a lack of ability to push and sustain decent brightness levels. You'll also want 4K, in an ideal world, 8K would be even better, but we are where we are.

> deep blacks

CRT blacks were really not that deep unless you're sitting in the dark and there is nothing else on the screen. It also depended upon model, coating etc. Even in perfect scenarios, contrast in mixed scenes was "meh" at best.

> High resolution OLED can come close

So far my experience is that it can not, as it's simply not capable of the brightness required, but it does offer nice blacks yes and better than LCD motion (though just barely due to sample and hold.)

I'd say the biggest remaining issue honestly is the motion blur inherent to sample and hold. As close as the more advanced shaders are getting today, it all falls apart when the image starts to move. Retroarch supports BFI, but its not as useful as it sounds for various reasons sadly.

For now, I retain my broadcast CRT's, but I do hope to get to a point eventually where I could get rid of them. Though I suspect by the time such a technology arrives and is useful, i'll be old enough that i'll probably have stopped caring.

My GF would love me to give up CRT's as I have a room full of them which she tolerates, but hardly loves :|
