The format currently expected by devices and sample display
application for BGR_565 is actually RGB_565 format with bytes
swapped (not B / R swapped). That is:
PIXEL_FORMAT_RGB_565:
* @code{.unparsed}
* 7......0 15.....8
* | gggBbbbb RrrrrGgg | ...
* @endcode
current PIXEL_FORMAT_BGR_565:
* @code{.unparsed}
* 7......0 15.....8
* | RrrrrGgg gggBbbbb | ...
* @endcode
This is explained in both st7796s display driver but also is
what is generated by the sample display application. As a video
format (ex: V4L2), such format is not mentioned as BGR (for
which R and B are swapped) but RGB_565X.
Within the whole Zephyr tree, rename the curremt BGR_565 format
into RGB_565X in order to emphasis that this is a byte swapped
format rather than a B/G component swapped format.
This also correct the description of the format in display.h
file, which wasn't correct based on what was being used by
display driver or sample display app.

Swap 16 byte color data from little to big endian format. When
|
|
this Kconfig is enabled, the DSI expects RGB565 data in little endian
|
|
format, which will then be byte swapped.
