Definitely I can tell you, because I create my own update rollups and make monthly test installs in my VM, so that the support for TLS 1.2 works for IE8 with KB4230450 without previous updates KB4316682 and / or KB4103768. Condition is that KB4019276 is installed!
The two registry entries
HKLM,"SOFTWARE\Microsoft\Internet Explorer\AdvancedOptions\CRYPTO\TLS1.1","OSVersion"
HKLM,"SOFTWARE\Microsoft\Internet Explorer\AdvancedOptions\CRYPTO\TLS1.2","OSVersion"
should be deleted so that the possibility exists to activate TLS 1.1 and TLS 1.2 in IE8.
Update:
The version number was not changed, but the creation date. Think in a binary comparison, there are certainly some differences.
In this case, because of the same file version, the update KB4230450 can not be found when checking for updates if KB4316682 is installed.
