You know, after I discovered the "Teal & Orange" affair, you will watch movies anymore with the same serenity... "Was that sky really teal? Was that face so orange?" (^^,) I'm a proud owner of many (if not all) laserdiscs that are free from T&O, and I'm happy!
If I were a powerful movie business V.I.P., I should impose a new standard for the next 4K BD: the movie MUST be released with discrete luma and chroma, and, if the movie was previously released with different color timings, each one MUST be included... should we start a petition right now?
