It seems that there is a validation in QGIS master (OSGeo4W) that is preventing SAGA LTR to start, when SAGA 2.1.2 is also installed.

So, when SAGA 2.1.2 and 2.3.2 are both installed with OSGeo4W, SAGA does not show up in processing, and log messages says:

Problem with SAGA installation: unsupported SAGA version found.

I think this is related to line 71 of SagaUtils.py

folders.append(os.path.join(os.path.dirname(QgsApplication.prefixPath()), 'saga'))

If SAGA 2.1.2 is installed, it uses it's path, and SAGA does not load, because is blocked by the validation of the line 87 of SagaAlgorithmProvider.py

if not version.startswith('2.3.'):

If SAGA 2.1.2 is not installed, then SAGA loads ok.

Anyway, it only loads SAGA Split RGB bands algorithm.
