EFB Performance: True vs. Magnetic

Could I confirm that the EFB performance pages use magnetic heading for the runway and true for the METAR?

For Cape Town (magnetic variation 26 degrees West) I noticed that the true wind from the METAR is inserted into the performance page when syncing:

But the runway heading is magnetic:

If the EFB were comparing apples with apples, it would need to use 156/17 magnetic for the wind, or is the variation taken care of in the background?
