Ok, lets us recapitulate the literature:
All the big German ships were designed with a bow with a straight stem and not much flare (outward bending frames forward). All of them except of two, Lützow and Admiral Graf Spee, got the Atlantikbug (Atlantic bow) to improve their seakeeping and make them less wet forward. Although some of the ships got the Atlantikbug before being completed, several were converted afterwards. These conversion had according to the literature also the feature that the frames were bend more outward (vergrößerter Spantenausfall). See e.g. Wikipedia:
Quote:
Auch dieses Schiff wurde (wie die Deutschland) im Winter 1939/40 zum Schweren Kreuzer umklassifiziert. Gleichzeitig wurde ein umfangreicher Umbau vorgenommen. Das Vorschiff wurde verlängert und bekam einen größeren Spantenausfall. Außerdem wurde der große Gefechtsturm über der Brücke ausgebaut und durch einen schlanken Röhrenmast ersetzt, und damit dem der Lützow (dem vorherigen Panzerschiff Deutschland) angeglichen.
https://de.wikipedia.org/wiki/Admiral_ScheerThis was part of a conversion, which should have been executed for all three ships of the Deutschland class. The purpose of the conversion was to reduce top-hamper, to improve the seakeeping and to overhaul the diesel (see e.g. Die Panzerschiffe der Kriegsmarine by Siegfried Breyer). Because of the war that conversion was not executed as planed, but it was executed for Admiral Scheer, because her engines required an urgent overhaul (therefore she could not be deployed at the start of the war). During this conversion also the foreship was modified and she got the Atlantikbug. Her sistership Lützow was not converted to the same extend, e.g. she did not got the Atlantikbug, but only a much more limited modification of the stem. That is visible by two characteristics: the amount of flare (outward bending of the frames; not only of the stem!) and the position of the anchors.
What kind of evidence do we have that the modification was more extensive than just the modification of the stem? Obvious are the anchors. And obviously the frames bend outward as seen at the photo linked by Miguel:

The bow looks very similar to other ships, which got the Atlantikbug, e.g. Admiral Hipper, Blücher, Prinz Eugen, Scharnhorst, Gneisenau, Bismarck, and Tirpitz.
If the frames bend more outward, the expectation would be that the deck is wider. And that is exactly what we see on the drawings by Eric Leon in German Naval Camouflage Volume One 1939-1941:

(top Admiral Scheer 1935, bottom Admiral Scheer 1940)
Here is the deck wider. Miguel wrote that I scaled the drawings wrong. Ok, but please check the width of the hull midships on both drawings and the dimensions of the forward 28 cm turret. It is the hull, which was modified and this modification was extensive, even though it was executed in a very short time. But that was the execution of a modification, which was planed anyway and which was also done for most other bigger German ships.
By the way: the hull of all three ships of the Deutschland class was different. All had different beam and side armour. And all had a different bow in their last fit: Lützow only got a modified stem, Admiral Scheer got a Atlantikbug, and Admiral Graf Spee was never modified.
