What issues?
Only seeing this now. Regarding the digital projectors there are lots of issues I have seen but my favorite was a Sony 4k projector with a 4k DCP that looked soft as hell. The reason was that nobody bothered to put the proper 4k 2D lens on, they chose to show the 4k DCP with the attachment for 3D! This was after i called asking if they were showing the 4k DCP with the projector - nobody had bothered to tell me that they would show the movie with less than half of its resolution.
Also focussing for digital projectors often is only so-so and even the framing can be significantly off even though the projectors now have zoom lenses.
The color temperature now has to be read off the screen and the projector adjusted accordingly in order to arrive at the proper values, the same goes for shading - this is very often skipped entirely for the color temperature and I will not even go into the need for some projector types to be readjusted with rather high frequency.
I could go on but these are some highlights.
I will not even mention that the average ON/OFF contrast of digital projectors in commercial cinemas is less than 2000:1 - it is horrible but it is also a design flaw and not a setup flaw.
