I'm not sure about those numbers. The Quantum M series 50" (2019) has the following clearances. This was important for me so I could place a sound bar between the feet and under the screen. Where the feet touch the surface there is 37 inches between the left and right feet. However they are designed at an inward slant. Where they connect to the TV body the distance between the feet is only 34 and 1/2". The height from table surface to bottom of the tv body is 2.5 inches and no more. If your question is really about depth, the feet are as follows. From front of foot to back of foot is close to 10 inches. (10.1) Installed the front of the foot will protrude from the front of the tv by approx. 3" and the back of the feet will extend about 4" beyond the back of the tv body. This might sound confusing but read it slowly and in part.
