I personally believe that you were very kind to let me know. But at the same time I must say that I have actually tested it several times (well, three files, actually) under Windows and it worked as expected: was I just lucky?
So... I used open because it seemed the quickest and cleanest WTDI, but what do you propose as a workaround or solution? (Short of manually open()ing the files of course...)
Update: I just actually checked with one single jpeg image and found an actual example that supports your claim. Incidentally, I would say that open.pm's docs do not make it clear enough that it won't work with <>.

By the way, I found open doesn't work on open(my $fh, '-') either.

I personally believe this is too bad. In principle it's such a wonderful pragma! Perhaps you should file a bug report. As far as open not affecting *ARGV is concerned, I would still consider that a bug too, since the documentation clearly says:
The open pragma serves as one of the interfaces to declare default "layers" (also known as "disciplines") for all I/O.
(Additional emphasis is mine.)
OTOH, it also says:
Any two-argument open(), readpipe() (aka qx//) and similar operators found within the lexical scope of this pragma will use the declared defaults. Even three-argument opens may be affected by this pragma when they don't specify IO layers in MODE.
(Additional emphasis is mine.)
Here, it is to be noticed that:
- it talks of "two-argument open(), readpipe() (aka qx//) and similar operators found [...]" which may be interpreted to exclude implicit "versions" of the same functions/operators;
- that emphasized "may" is at most ambiguous and I would like to know which is the actual behaviour.
As far as the second point is concerned, I also think that it would be more reasonable to have three-argument opens always alway affected by the pragma, since it just "declares default "layers" for all I/O" and IMHO if they specify IO layers in MODE, then the latter ones should be simply stacked over the default ones.
