If you're happy to ignore the warnings then it's fine. Basically the J2K data uses 14-bit precision, but the dataset has 16-bit. I've since reconsidered the need for them since it's (mostly) irrelevant for the end user so they'll be gone in v3.0.
pydicom.config.image_handlers isn't a valid attribute and so doesn't do anything. pydicom.config.pixel_data_handlers (ooof, that function signature) or Dataset.convert_pixel_data(handler_name="gdcm") then Dataset.pixel_array should work a bit better.

Will it affect the image? As in would the image be different when viewed?

It depends if you're turning off some of our corrections and which plugins you're using, but generally speaking it has no effect.
Where "corrections" means reversing some of the less than desirable behaviour of pillow, or J2K data encoded using incorrect parameters.
