Since the thread title is "DLP contrast worse than 5 years ago?" and not "DLP native contrast worse than 5 years ago?" I'll rephrase my question:
Thanks to the dynamic laser dimming we can probably expect contrast surpassing the native one and a more stable performance than with a dynamic iris?
Frankly I couldn't care less whether the native contrast of the DMD is piss-poor or not as long as 'dynamic' intervention yields an overall better contrast impression without noticable hick-ups.
