The measures we have them, but how much are they meaningful in real life, in the real world...

At dpreview.com they have a gallery for the Canon RP which features a few under-exposed shots that could serve as test examples.

For instance, this shot at base ISO looks pretty bad once adjusted; original shot:

The adjusted one which becomes quite noisy and reminds me of what I get with MFT:

It would be interesting to see the result of a similar shot with a Nikon Z6 or a Sony A7III for instance.

this test is more about ISO invariance than dynamic range, I guess we are mixing things a little bit
For ISO invariance yes EOSRP is a loser a picture taken at ISO 400 and pushed one f stop has much more noise than a photo taken natively at ISO 800, that's why plenty of  Canon users have the habit of shooting  to the right and then decrease exposure in post processing to overcome this issue, to add insult to the injury  Canon sensors already have more noise in  shadows areas than the rest of the frame...  shooting to the right solves this.
In bright daylight, instead of 1/100 f16 at ISO 100 use 1/50f16 ISO 100 and push exposure minus one f stop in RAW  you will have much better results
For landscape when shooting RAW I do my metering using live  histogram taking care of not to have clipped highlights, when you know your gear shortcomings and know how to overcome them, they are not shortcomings anymore
will show you all this as soon as I have some time to shoot and edit pictures, hopefully this week

Well, that's my point: if the scene has more DR than the sensor can capture, you'll be in the same situation as in the example above. You'll expose to the right to prevent the sky to be blown out, but then end up with under-exposed areas in the foreground.
A sensor capable of recording a wider DR will mitigate this a bit and give better results.
