This latest post seems a long way from the specific concerns you raised in starting this thread.
These PL / LR back-and-forth issues have been the subject of a number of other threads, e.g., here: Odd colour shifts when exporting DNG (with optical corrections only) from Wide Gamut Colour Working Space.
Please consider moving the discussion there or to another thread where the heading might attract more targeted interest. Of course, you could always start a new thread if you feel your issue is sufficiently novel. Thanks.
