That is not the case: when plymouth works ok if we press Esc we see system
messages colored [Ok] and screen actually in graphics mode: pressing Esc again
- immediately back to the splash so no graphic mode changed. In our case we do
not enter to graphics mode - PC remain in text mode and system messages are not
colored in text mode like in terminal by Ctrl-Alt-F1.
