So instead of resizing the picture and possibly introducing artifacts they simply crop the frame.

Is there any evidence of this happening? My understanding is 1.85:1 movies are shot 1.37:1 and matted for projection and are just matted slightly less for DVD/Blu-ray release. 2K masters are 2048 pixels wide and whatever height they need for the AR.

Also, most movies which are listed as 2.35 on the package are really 2.39 on the disc and someone just never got the memo Cinemascope changed its ratio slightly several decades ago.
