[Brightcolours]

You are proving my point. The 1st you made into a fantasy landscape, straight out of fantasy movies. The 2nd looks unnatural, making the viewer wonder what exactly is reflecting that light on the back of the people sitting on that bench, light should not be that omni directional, with our brain telling us there can't be that back light combines with the odd software illumination of the subject. And why you think this is out of the realm of the RP sensor is a mystery to me, anyhow.
The 3rd, also strange light that does not really work, but the best of the three and fine for a family album, ofcourse. But not a great image, due to the light conditions and/or choices in post processing.

In many cases it is almost the opposite: for attractive images, in respect to DR, "the less" the merrier.






To recap: The images you posted and what you did with them of course can be made with a Canon EOS RP. The results are less than attractive, with odd, flat light that puzzles your brain (due to unexplained omni directional light effects). As photographer you should embrace light, which includes shadows. No reason to be afraid of shadows, and indeed, the dark.

You do not make a great case for "the need" for very high DR.
