Right, but it's also the only
thing about anamorphic encoding that benefits picture quality that is unique to anamorphic encoding. Everything else, bit rate, scan quality, etc, etc, is universal to any format or storage method.
Doubt anamorphic BD encodes will ever come to the market, but there could be a 2560 x 1080 BD with higher bandwidth (75Mbps ?)somewhere in the future.
I doubt it, I think any hope for better than BD whether it be anamorphic encoding higher resolutions, whatever, will have to come from the "next" format, be it some future disc based format, or IMO more likely, a future "niche" digital distribution system.
While true that digital distribution is primarily a boon for convenience seekers, it also reduces distribution costs so it could lead to future Criterion-like outfits popping up distributing special versions to quality nuts.
There is a finite amount of information in the master(2 or 4k), however, the amount of detail addressed to the encode will vany depending on the bitrate applied by the compressionist.
The detail for example found on a DCi (2k) encode would be significantly greater than the BluRay version of 1920 x 1080, due to DCi higher bandwidth and lower compression.
It's not nearly that simple, BD has much bigger problems than bitrate when it comes to qualty, first and foremost is the master quality. Probably the next biggest is the limitations of 8-bit encoding, and 4:2:2 color sampling, and lets not forget the smaller gamut of consumer home video. And then maybe the last one is the significant difference between DCI gamma and home video ~2.2 gamma.
You can crank up the bitrate all you want on a BD, but the fact of the matter is it's really not going to do a lot. BD already has more than enough space given the above limitations, more bitrate will not make much difference given BD's non-bitrate constraints.
