At this point it's one of those things that comes down to taste rather than authenticity. Pixel-art games have continued on and had their own development arc between indie gaming and the remastering trend, and they've all had different approaches to it. Even people like me that grew up with CRT displays have had their tastes shaped by years of gaming on different tech.

I haven't gotten my hands on a CRT since I left my last one behind 15-ish years ago, but I do get a bit of a nostalgia buzz from the CRT-Royale package on a 4K display. When that's not available I tend to use one of the scalers because I really don't like aliasing, and high resolution displays really bring out the blockiness. That sort of thing is sacrilege to some people. Everyone's a little different.
