It seems not much changed over the years
I'm OG large screen HT nut, been gone a long time. Still looks like CIH and anamorphic lens projector systems remain a niche for 1% videophiles. As with all digital technologies, projector native resolution and light output have improved dramatically from the old high tech line doubled image feeding a CRT FP days. lol.
It seems like today's mainstream native 4k UHD projector can throw a very nice sharp and bright 2.35 image onto a 10 foot screen in full light controlled venues, especially for movies. The increased resolution and brightness may offer more for sport fans.
The specialty high quality design and production anamorphic lens remain a costly hurdle as it always has. For home HT, making the decision to go down this path, chasing single digit improvements for the multiple factors increase in cost, seems one that even fewer venture into.
