Really Really make RZ logo accessible for real this time

Also make version number more accessible

Some observations about VoiceOver:

• Numbers with two components separated by a period are spoken using the word "dot." This is a bit odd for file sizes, which are thus spoken like "twelve dot five gigagbytes."
• Numbers with more than two components are spoken with a pause separating each digit. Stepping character by character, the user hears "period" spoken.
• On the About screen in Settings, the OS version number is spoken as "ten dot zero point one." Meanwhile, stepping character-by-character, it speaks the string with periods.
• "9.0.4" is spoken "nine zero four" whereas "10.0.4" is spoken "ten dot zero point four." This is obviously a special case for numbers with three components separated by a periods and a first component ten or greater (yes, it works with "11"). I wonder how it behaved on iOS 9, but do not have a test device handy.

Given this behavior, I'd either spell out the version, as you did, substituting "point" for the first period, or leave it as a number and file a Radar.
