I know the EE Blu-ray has its issues, but in terms of detail, natural grain, and compression, it’s superior to the theatrical release in my opinion (and if memory serves, the audio on the theatrical Blu-ray was the same overcooked track from the DVD). With your color corrections, which look great, I think I can deal with a bit of black crush to get all the other benefits of the EE upscaled to 4K (assuming you’re not taking a stab at addressing the black crush also).
Really looking forward to this.
