Does out of Focus (OOF) rendering stay the same with in camera crop?

Question I’ve been pondering:

Let’s say I’m photographing any given subject with my R5 and my RF 70-200 f2.8. I’m taking a photo at 200mm f2.8. I decide I want to use the 1.6x in-camera crop to get an equivalent FOV of 320mm. Is my out of focus rendering still f2.8, only now at a FOV of 320mm?

When viewing images, it seems like it is. Some have argued with me that the OOF/Bokeh is closer to f4 or f5…but I don’t see how this is true if it’s just a crop of the original f2.8 image…If I am wrong, what am I missing?

(I’m not concerned with the megapixel loss… I’m mainly wondering if I still have the same OOF rendering I had with the 200mm f2.8 image)

Of course it doesn’t change, what those people mean is that that amount of bokeh you have cropping at 200mm 2.8 would be equivalent to a picture without crop from a 320mm f4 lens.
