As of 1:31AM Philippine Standard Time, 10 March 2015, the
official website does not indicate that the Denim* update is available to the "general public" (those not in PFD) for the L920 and L1020. Denim is, however, available already for the L520.
What you are referring to is a
known bug for the Extras+Info page for those who have downloaded the "latest" available OS "preview" for those who had their phones enrolled under the PFD program. The bug will show "Denim" when PFD is disabled, but it will revert back to "Cyan" once PFD is re-enabled. You won't even need to reboot the phone in most cases for the bug to manifest itself.
I, myself, have observed minor speed improvements with my L1020 in just disabling PFD, but my results are inconclusive - sometimes it will be faster without PFD, sometimes it will be slower.
*- The update received through PFD is already "Denim" although PFD still says it is "Cyan". The reason could be that there was no change in the firmware revision number from Denim to Cyan (as reported by many users, will vary for some devices), only an update in the OS version, whereas the nomenclature (Amber, Black, Cyan, Denim) was used mainly to refer to firmware + OS updates (not OS only updates). You may read further about it in the fora, but I think the revision numbers matter more than the "name" of the update.
Thanks for the message. I'm still not sure what the status is, as the MS Denim update site is not correct or consistent.
Below is what shows on the site for the 520, 920 and 1020, the three phones we have. I first noticed on the 520 because it had the updated OS and Firmware versions as listed below, however it still showed Cyan, even though the site clearly says Denim for these version.
As mention in my initial post, I turned off Develop Preview and restarted the phone. After restart, Extras+Info now showed Denim.
When I went to my 920 and 1020, they had the same updated OS version as the 520, not the one listed below which is still listed on MS website. I have a later OS version matching that of the 520 with Denim. The firmware versions are the same as what is listed below and still on the MS website.
Just for kicks, I tried the same process, turning off Developer Preview and restarting. Sure enough Denim appeared.

As I mentioned, I have noticed significant speed improvements in the saving process after taking photos, which use to seem to take forever. Opening of camera app may be slightly improved, and picture taking also. but these not as significant as the saving time and readiness for another shot.
I'd really like to hear from others in Phils on your experience, i.e. if you were able to receive Denim or not, and if you have, any improvements?
Let's hope for something official on this from MS soon.
