Canon 5D Mark III rear LCD stays on and INFO screen changed

Question

On my Canon EOS 5D Mark III (firmware 1.3.5), the rear LCD no longer turns off when I put my eye to the viewfinder. Also, the default rear display while the camera is ready to shoot has changed, and now I only see the shooting information screen after pressing the Q button. How do I get the old screen back, and is there a setting to make the LCD turn off automatically when using the viewfinder?

Sometimes, a short look into the camera's manual is quite helpful. ;-)

"First problem: the LCD screen does not turn off when I look at it from the viewfinder."

Pages 19 & 20 show the nomenclature of all important parts on the backside of the camera. As you can see, there's no eye sensor. _{The light sensor is for the LCD-screen's brightness auto-adjustment.}

^{Screenshots from the 5D3's manual (linked above), merged and slightly modified by me.}

"Second problem: my screen was like this before."

Again, the manual is of help: see p. 342 -343:

When you press the INFO-button while the camera is ready to shoot, you can display [...] Shooting Settings. [...] Under Camera settings¹ tab 3, INFO button display options enables you to select the options displayed when the INFO button is pressed.

¹ _{Camera settings: That is the yellow menu with the wrench/spanner as symbol. (See p. 360)}
