Definitely interesting to see a comparison like this!
Personally, I'm not really a fan of these types of things as there's rarely a fair comparison unless the user is an expert in both engines. In most cases, the images are a reflection of the artists ability with different engines rather than the software themselves. That being said I think you did a pretty good job trying here!
From looking at the lumion images, I can pick out a few points that could be altered in order to close the gap. Interestingly enough, the lighting temperature appears fairly close however the lamp/hyperlight/GI settings appear to be causing some issues with spots and shadow irregularities in the Lumion version.
The materials in the Lumion images are quite different to the corona image. The reflectivity values are different on several surfaces and there appears to be very little specularity adjustment (corona handles fresnel very well). These things make a huge difference to the accuracy of a material and the way that light interacts with everything. The sofa in the Lumion image in particular caught my eye as it appears almost plastic compared to the Corona equivalent.
The colour settings in the Lumion render are also quite different. With significantly lower contrast, and higher shadow brightness (a common problem when users try to artificially light their scenes). Often we become a little fixated with "lighting" a scene that it becomes polluted (something I'm guilty with regularly). It's always important to remember that shadow is as important as light is and I think this is where studying real life references is crucial. The saturation levels also vary between the two samples, both in the overall image and the materials themselves.
Just my 2c on a very interesting conversation!
Anyway, nice job on both of them individually! It's a nice design and i think I've commented on this image elsewhere but I really like the material on the TV unit! good stuff!
