As others have replied, no. However...

Your Blu-ray disc is mastered from the same elements that the movie theater file (DCP) is mastered from; the Blu-ray having about 94% of the same resolution as the DCP. Depending on the screen size, a properly mastered Blu-ray disc will compare very favorably to a DCP.

Many home theater aficionados own TVs and projectors that have better specs than commercial theater projectors (stronger contrast, better black levels, etc). People in this category can rightly claim that a Blu-ray disc looks better in their home theater than the DCP they saw at the local multiplex.
